This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during servicing of the unit. 1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all times. Do not stare the laser beam at any time. 2) Do not attempt readjustment, disassemble or repair of the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION : Use of controls, adjustments or preformance of procedures other than those specified herein may result in hazardous radiation exposure. 1. Critical Components Information Components having special characteristics are marked Z and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by 0.15F. GLeakage current must not exceed 0.5mA. I TO SERVICE PERSONNEL WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. GBe sure to test for leakage with the AC plug in both polarities. Laser Emitting conditions: 1) When the Top Cover is removed, and POWER SW is turned to the ON position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period ! If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser emissions. 2) The laser power level can be adjusted with VR on pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust this laser level control unless instruuction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device.

Before installing the CDR mechanical unit, check that the jumper pin on its rear panel is inserted in the MAS- TER jack. b. Install the components of the CDR mechanical unit cor- rectly in the reverse order of the removal. c. Use special care for the power cable of the CDR me- chanical unit. If it is connected in reverse, the mechani- cal unit will be damaged and fail to operate. The end of the power cable with a red line is the No.1 pin side (+12V). Connect it to No.1 pin of the DC power input connector. d. The No.1 pin side of the IDE cable of the CDR mechani- cal unit can be identified by a red line. Connect it to No.1 pin of the IDE interface connector. 4. Operation Check after Installation 1) Checking after turning on the power When the power is supplied, the CDR mechanical unit executes self-diagnosis automatically. If an error is detected in the initial self-diagnosis, LED segments (LED601: ON/DISC, LED602: Read/Write) on the front panel of the mechanical unit light up (in or- ange) simultaneously and remain on. If a malfunction has occurred, power on fails. (IDE com- mand error) 2) Checking when malfunction has occurred a. Check each cable for correct connection. b. Check the power supply voltages. (Measure voltage at the power connector of the mechanical unit.) c. Check to ensure that the jumper pin on the rear panel is inserted in the MASTER jack.

Turn off the power to check the condition of the CDR drive section. 3. Disconnect the IDE cable. 4. Turn on the power and check the CDR drive section for proper operation. (Check the condition of the CDR drive.) The CDR drive should operate by itself. (Focusing, disc motor revolution) Operation failure means defective CDR drive. 5. Turn on the power again and check the CPU and FL display for proper operation. Does the FL display light up after a few seconds? Is the FL driver accessed? (FL DATA, FL SCK, FL N CS) 6. Turn off the power and connect the IDE cable. 7. Start the TEST program and check the condition of the main P.C.B.(by using the self- diagnosis function). When skipping occurs from time to time, playback/recording is disabled. 1. Using a standard disc (TDK CD-RXA74 or TDK CD-RWXA74), check if recording and playback are executable. CAUTION: How to handle discs Handle the disc with special care not to scratch it or make it dirty. Also do not expose it to ultra-violet rays when keeping it in storage. (Greater care should be used than when handling a CD disc.) CD-RW74 can be used repeatedly but use a number of 20 times as a rough standard for the limit. If the CD-R is a self-record/playback type, it can be reused (for additional recording) unless it is finalized. (Nothing can be recorded additionally if finalized.) The CD-R disc which has not been finalized cannot be played back on a general type CD player. To play back the CD-RW, an applicable type CD player must be used.
